Upfitter Switch Fuse Block Output Pigtail Connector
If you’ve ever bought a GM Upfitter Switch Kit for a Silverado EV, Sierra EV, Hummer EV, or Colorado/Canyon, you know the frustration. GM gives you a dummy plug at the fuse block output with no wire leads and zero instructions. Unless you have specialized crimp tools and terminals, you’re stuck.
The 404 Parts Plug and Play Pigtail Connector fixes that. This simple harness plugs directly into the factory Upfitter Switch Fuse Block output port for a fast, clean connection. Built in house by 404 Parts using OEM connectors, terminals, weatherpacks, and 14 gauge wire, it matches factory spec and takes the guesswork out of hooking up your lights, pods, or other accessories.
Compare this to GM Equivalent Part# 19367561, which lists for $92.58 at the dealer — nearly a quarter the cost of the entire switch kit — and you’ll see why our version is the smarter choice.
